Question: We have seen that, for a binomial distribution with n trials, each with probability of success P, the mean is as follows: X = E[X]

We have seen that, for a binomial with n trials, each with probability of success P, the mean is as follows:
μX = E[X] = nP
Verify this result for the data of Example 4.7 by calculating the mean directly from
μX = ΣxP(x)
showing that for the binomial the two formulas produce the same answer.
